IPC: G21C15/243
Filed: 1964-09-29
Abstract: 1,022,947. Cooling reactors. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Sept. 29, 1964 [Oct. 4, 1963], No. 39629/64. Heading G6C. In a boiling water reactor, the coolant is forced to circulate upwards through the vertical fuel elements. Deflectors in the coolant stream, between the fuel elements, induce helical flow lines in the coolant flow. The circulation velocity is adjusted so as to produce a lateral centrifugal acceleration in the coolant greater than a selected value. The arrangement is suitable for marine reactors which are subjected to changing accelerations which would otherwise tend to disturb the coolant distribution in the core region. In the embodiment described the deflectors are formed of helically twisted strips, the pitch of the twist being a function of the coolant velocity.

Title: Improvements in or relating to liquid mixtures of epoxy alkyl ethers
IPC: C08G59/22
Filed: 1960-11-18
Abstract: A composition comprising a major proportion by weight of at least one bis(epoxyalkyl) ether of 2,2-bis(p-hydroxyphenyl)propane and a minor proportion by weight of at least one bis (epoxyalkyl) ether of 1,1-bis(p-hydroxyphenyl) ethane and/or of at least one bis(epoxyalkyl) ether of bis(p-hydroxyphenyl)methane may be cured by incorporation of a curing agent such as an amine.  The epoxyalkyl groups are preferably glycidyl groups.  Other additives may be incorporated such as polyhydric phenols, other resins, fillers, dyes and pigments.ALSO:A liquid polymerizable composition which is stable towards crystallisation comprises a major proportion by weight of at least one bis(epoxyalkyl)ether of 2,2 - bis(41 - hydroxyphenyl)-propane and a minor proportion by weight of at least one bis(epoxyalkyl)ether of 1,1-bis(41-hydroxyphenyl)-ethane and/or at least one bis(epoxyalkyl)ether of bis(41-hydroxyphenyl)-methane. The composition may be prepared (1) by mixing together the preformed components, (2) by reaction of a mixture of the corresponding bis(41-hydroxyphenyl)-alkanes with epoxyhalogen alkanes, or (3) by dehydrohalogenation of a mixture of the corresponding halohydrins. Preferred compositions contain 3-20% by weight of the ethers derived from methane and/or ethane and contain only a small proportion of polymeric material.  The epoxyalkyl groups are preferably glycidyl groups. Bis(41-hydroxyphenyl)-alkanes are preferably converted to their bis(epoxyalkyl)ethers by reaction with an epoxyhalogen alkane, especially, epichlorohydrin, in an alkaline medium.  A large excess of epichlorohydrin is usually used and the alkalinity is obtained by the use of an aqueous phase containing an alkali metal hydroxide and/or alkali metal salts of one or more of the bis(41-hydroxyphenyl)-alkanes to be etherified.  The water content of the reaction mixture may be kept low by azeotropic distillation, the epichlorohydrin being continuously returned to the reaction vessel. The bis(halohydroxyalkyl)-ethers are prepared by method (2) above using a non-alkaline reaction medium, or by reaction between dihalogen monohydroxy alkanes and the corresponding bis(41-hydroxyphenyl)-alkanes.  In the example, a mixture of 2,2-bis(41-hydroxyphenyl)-propane and bis(4-hydroxyphenyl)-methane is dissolved in epichlorohydrin, heated, and aqueous sodium hydroxide added; the water, epichlorohydrin and inorganic compounds are removed and the product is treated with aqueous sodium hydroxide to convert any chlorohydrins present into epoxides; the product remained clear after storage for 1 year.  Curing agents may be added to the compositions (see Group IV(a)).

The spokes 7 have a trapezoidal cross-section in the plane perpendicular to the hub axis and the sides of the spokes have ribs 8. The wellbase rim is formed by bending the upper end of the wall 5 outwards (5<SP>1</SP>), Fig. 7 (not shown), so that it co-operates with the flange 6. The parts 11 between the spokes are removed by machining or stamping and the surface of a flange 9 between the spokes is machined perpendicular to the hub axis. The hub is bored (14), Fig. 9 (not shown), and the wellbase rim rolled between pressure rolls at room temperature to form a shaped rim (18), (19), Fig. 12 (not shown). The rims (19) of the well are made to have a greater thickness than the base (18). After this final shaping the hub is bored (21), (22) for reception of a tyre valve and wheel retaining bolts respectively. Examples of suitable light metal alloys are given.

Title: Improvements in and relating to control means for fluid-operated engines producing rotary power

Filed: 1958-12-11
Abstract: 865,278. Fluid-pressure engines; regulating and controlling. PETERS & CO. Ltd., G. D. Dec. 10, 1959 [Dec. 11, 1958], No. 40062/58. Classes 122 (3) and 122 (4). In fluid-pressure engines required to operate for a limited number of revolutions in one or either direction a member driven by the engine is displaceable in accordance with engine revolutions to actuate a fluid-controlling valve prior to the stopping of the engine, thereby to cushion operation and decrease engine speed. The shaft 4 of a compressed-air swash-plate engine has an extension 10 supported in a bearing 11 and having a threaded portion 14 between two spaced axially-adjustable abutment discs 15 and 16 locked in position, as by a clamping bolt 17, and each having a radial abutment 18 and 19, respectively. A nut assembly comprising a sleeve 22 and a radial flange 25 is threaded on the shaft portion 14 and has radial abutments 20 and 21, respectively engageable with the abutments 18 and 19. A ring-part 26 at one end of an arm 27 is clamped between the flange 25 and a friction-plate 23 by a helical spring 24. The opposite end of the arm 27 is slidable in a channel section portion 29 of a rocker plate 28 pivoted about the shaft axis and having ears 30, 31, respectively engageable with ends 32, 33 of exhaust valves 34, 35 fitted with restricted by-pass passages 36, 37 adjustable by studs 38, 39. When the engine is rotated by compressed air supplied through the engine valve-gear (not shown), the nut assembly travels along the threaded part 14 until the abutment 20 or 21 engages with the abutment 18 or 19 on disc 15 or 16 which causes the nut 22, 25 to rotate and carry with it the frictionallyengaged arm 27 to pivot the rocket plate 28 and close the appropriate exhaust valve 34 or 35 so that further exhaust continues only through the restricted orifice 36 or 37. This action occurs before the engine is stopped so that the engine continues to operate at reduced speed, with slipping between the flange 25 and ring- part 26, until it is brought to rest by the engine valve-gear. Upon reversal of the engine the nut assembly travels in the opposite direction until it meets the other disc and the other exhaust valve is similarly closed.

An ion accelerator utilizes a pulsed beam and a series of ion permeable accelerating electrodes 5, 6, 7, 8 which are connected to a direct high-voltage source 11 through individual high resistances 13, 14, 15, 16. When the ions reach an accelerating electrode its voltage is reduced practically to zero and the ions are accelerated by the high-voltage difference between this electrode and the next accelerating electrode. This action recurs down the tube. The ion source S is of the type described in Specification 913,956 and the ions are initially accelerated by the ion extracting electrode 4. The accelerating electrodes may be in the form of grids or centrally apertured discs. The spacing between the electrodes may increase down the tube to maintain a constant transit time between adjacent electrodes. Positive ions, e.g. protons or deuterons, or negative ions may be accelerated. Working details are given. The invention may also be applied to accelerators of the cyclic type in which the ions circulate in spiral or circular trajectories in a transverse magnetic field, the evacuated chamber being in the form of a ring of rectangular cross-section of relatively low axial height or of a torus.
